This patchset contains a driver for a Silicon Laboratories 476x seriesof radio tuners. The driver itself is implemented as an MFD devicescomprised of three parts: 1. Core device that provides all the other devices with basic functionality and locking scheme. 2. Radio device that translates between V4L2 subsystem requests into Core device commands. 3. Codec device that does similar to the earlier described task, but for ALSA SoC subsystem.

This driver has been tested to work in two different sytems: 1. A custom Tegra-based ARM board(design is based on Harmony board) running linux kernel 3.1.10 kernel 2. A standalone USB-connected board that has a dedicated Cortex M3 working as a transparent USB to I2C bridge which was connected to a off-the-shelf x86-64 laptop running Ubuntu with 3.2.0 kernel.
